In this manuscript the multifunctional multiferroic 0.6BiFeO₃-0.4PbTiO₃ (BFPT) thin films are presented as an interesting alternative for multifunctional photovoltaic applications. The compound is chemically and structurally stable at high temperatures and consequently reliable to work under difficult operating conditions, such as sunlight radiation. Nanostructured single-phased BFPT thin films were processed and their electric, dielectric, structural, and optics properties were characterized in this work. The films were used as active layers in a heterostructured photovoltaic arrangement, which proves their photovoltaic behavior. Interesting physical properties, as intrinsic photovoltage production (~ 1 mV/cm²) with excitation power (300 W) were associated to the high dielectric constant (> 220 at 1 kHz and room temperature), the existence of long-range electrical conductivity processes, and the presence of two band gap energies (at 3.95 eV and 2.51 eV) in the BFPT compound that enhance the light absorption with consequent photovoltaic generation in the visible light region.

在这份手稿中，多功能多铁性 0.6BiFeO ₃ -0.4PbTiO ₃ (BFPT) 薄膜被提出作为多功能光伏应用的有趣替代品。该化合物在高温下化学和结构稳定，因此可在恶劣的操作条件下可靠地工作，例如阳光辐射。在这项工作中，我们对纳米结构的单相 BFPT 薄膜进行了处理，并对它们的电、介电、结构和光学特性进行了表征。这些薄膜被用作异质结构光伏排列中的活性层，这证明了它们的光伏行为。有趣的物理特性，如固有光电压产生 (~ 1 mV/cm ²) 与激发功率 (300 W) 与高介电常数（在 1 kHz 和室温下 > 220）、长程导电过程的存在以及两个带隙能量（在 3.95 eV 和 2.51 eV) 在 BFPT 化合物中，可增强光吸收，从而在可见光区域产生光伏。
